+Error detection refers to techniques used to identify changes to data during transmission or storage. It ensures [Data Integrity](/wiki/Data_Integrity) by revealing when information has been corrupted, often by adding [Redundancy](/wiki/Redundancy) that can be checked against the original data. These methods signal the presence of errors without necessarily fixing them.
